New types of data will give new challenges as well. The present paper highlights important concepts of Big Data. In this write up we discuss various aspects of big data. We define Big Data and discuss the parameters along which Big Data is defined. This
includes the three V's of big data which are velocity, volume and variety. The authors also look at processes involved in data processing and review the security aspects of Big Data and propose a new system for Security of Big Data and finally present the future scope of Big Data
